I have a 2000 toyota camry V6, Car is in excellent condition, I recently had engine light come on, I took it to Advance auto parts and they use the scanner and fault code was Oxygen Sensor Bank 1 (upstream). I replaced sensor and code was clear, ran car for a couple of miles then light came back on for Oxygen Sensor, Is there any other sensor or part that could be causing light to come back on.

Thanks

I would always recommend factory original parts, not after-market.
You may also have another diagnosis to verify that they gave you the correct information. Did they tell you which sensor or did they provide the actual diagnostic trouble code?

I would only use an OEM oxygen sensor, which is likely made by Denso. Make sure the pigtail connector has not been contaminated by oil, silicone spray, or even brake cleaner. If it has, it will continue to throw a code forever.

I have had experience with exhaust leaks before the O2 sensor causing a fault.

Thanks

Make sure you properly identified Bank 1; i.e., Bank 1 contains spark plug #1.
